Patented Jan. 21, 1936 UNITED STATES PATENT OFFICE LASTING MACHINE William Thomas Buckingham Roberts, Leicester, England, assigner to United Shoe Machinery Corporation, Paterson, N. J., a corporation of New Jersey Application February 26, 1934, Serial No. 712,914 In Great EritainMarch 24, 1933 22 Claims.

marginal portion of the heel end of an upper on a last inwardly over an insole or other shoe bottom part (hereinafter referred to generically as the sole) and with a heel-end-clamping device or heel band for clamping the upper materials about the heel end of the last prior to the operation of the wipers on the upper. If the heel-end-lasting operation ispperformed, as it sometimes is, before the sides of the shoe forwardly of the heel end have been lasted, or underk some conditions even if the lasting of the heel end follows the lasting of the sides, the heel band and wipers in their operation on the shoe may displace portions of the upper in such manner as to produce undesirable wrinkles or' ears of loose upper material immediately in front of the heel-end portion of the shoe-unless special precautions are taken to avoid this result as by driving tacks to fasten the opposite side margins of the upper materials near the forward end of the heel seat in proper positions prior to the heel-end-lasting operation.

An object of the present invention is to provide in a heel-end-lasting machine improved means for controlling the upper materials in such manner as to avoid the above-mentioned objectionable conditions without the necessity for preliminarily fastening portions of the upper by tacks. To this and other ends, the construction herein shown comprises, in a machine having a work support movable to present a last and shoe to the lasting mechanism, novel means mounted independently of the work support and movable automatically into position to hold the upperI materials in proper relation to the last and tol a sole on the last in locations adjacent to the opposite side edges of the shoe bottom approximately at the forward end of the heel portion of the shoe prior to any substantial clamping action of .the clamping means or heel band on the opposite sides of the heel end of the upper. As illustrated, this upper-controlling means comprises members which are movable widthwise of the shoe at its opposite sides. and under some conditions act to lay the marginal portions of the upper materials inwardly over the sole as well as to press them upon the sole in the abovementioned locations, these members being supported on arms which operate them by swinging movements about axes extending heightwise of the shoe. To insure against the formation of any ears of loose upper material between these upper-controlling members and the heel-lasting wipers, these members, in accordance with a 10 further feature of the invention, are so arranged that they engage portions of the upper thereafter engaged by the wipers in the wiping operation and are movedlengthwise of the shoe by the action of the wipers thereon. In accordance with still another feature of the invention, there are combined with the above-mentioned uppercontrolling members, in the construction herein shown, other members which clamp the upper at the sides of the last in locations spaced substantial distances heightwise of the last from the edge of the shoe bottom and assist in supporting the last and shoe against tipping movements in the lasting operation. As illustrated, each of these other members has means thereon for clamping the upper in locations spaced apart lengthwise` of the last and is itself arranged in ixed angular relation to the member associated therewith for controlling the upper at the edge of the shoe bottom as above described, both these members being mounted to swing as a unit about an axis extending lengthwise of the shoe to permit them to adjust themselves to the shoe.

The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawing and pointed out in the claims.

In the drawing,

Fig. 1 is a plan view of a portion of a machine in which the invention is embodied:

Fig. 2 is a view in front elevation of the parts shown in Fig. 1; and

Fig. 3 is a view mainly in left-hand side elevation of parts shown in Fig. 1 at the righthand side of the shoe.

Since the invention is herein illustrated as embodied in structure intended to form part of a machine of the same general type as disclosed in the above-mentioned Letters Patent, only such parts of the machine as it is necessary to refer to for an understanding of the invention are herein shown and will be particularly described. The machine is provided with a shoe-supporting jack I provided on its upper end with a last pin 3 to receive a last and shoe positioned bottom upward for the operation of the machine thereon. As is common in machines of the illustrated type, this jack is supported, by means not herein shown, for forward and rearward swinging movements, as indicated by arrows on Fig. 3, so as to receive the shoe in an idle forwardly inclined position yand to carry the shoe rearwardly to present it to the lasting mechanism. The jack is thus swung rearwardly by the operator and is then lifted by a treadle (not shown) until the heel end of the sole on the last comes into contact with holddown members 5 which serve to position the shoe at the correct height for heel-lasting wipers, hereinafter more particularly referred to, to wipe the margin of the upper around the heel end inwardly over the sole and press it upon the sole.

In the construction herein shown there are provided a pair of bell-crank levers 9 (Fig. 1) which are supported and operated in substantially thel same manner and by substantially the same means as the shoe-supporting bellcrank levers l98 disclosed in the above-mentioned Letters Patent. Instead, however, of serving only to assist in supporting the shoe and last against longitudinal and lateral tipping movements and against downward movement in the lasting operation, as in the ccnstruction shown in the above-mentioned Letters Patent, the bell-crank levers Si herein shown carry members which are arranged to lay the marginal portions of the upper materials inwardly over the sole, if the materials have not already been laid inwardly, and to press them upon the sole in locations adjacent to the opposite side edges of the shoe bottom at or near the forward end of the heel seat. For this purpose each bell-crank lever 9 has adjustably fixed to its forwardly extending arm Iii a small bracket I I which has therein a T-shaped groove I3 (Fig. l) extending horizontally along the arm, and within this groove lies the head of a bolt I5 which extends through the arm and has a nut Il thereon to clamp the 'bracket Il in fixed position on the arm. After loosening the nut il the bracket ii may, if necessary, be adjusted along the arm it for shoes of different sizes by sliding it relatively to the head of the bolt I5. Further to control the bracket II, the bracket is provided with a second horizontally extending groove in which lies a rib I9 formed on the forwardly extending arm Iii. arranged to extend laterally of the shoe is fixed in the forward end of the bracket II, and mounted to turn on this pin is an upwardly extending arm 23. The upper end of the arm 23 is bifurcated and it is provided in its inner face with a comparatively deep downwardly extending groove 253 (Fig. 3). A pivot 25 is mounted in the upper bifurcated end of the arm E3 to extend in directions lengthwise of the shoe, and mounted to swing on this pin is a depending rigid arm 2i which lies normally in the groove in the arm 23 in contact with the latter at the bottom of the groove. Integral with the arm 2 in angular relation thereto above the pivot pin 25 is a rigid arm 29 arranged to extend inwardly over the shoe bottorn, as more particularly hereinafter described, to press the marginal portion of the upper materials upon the sole adjacent to the edge of the A pivot pin 2i shoe bottom in a location at or near the forward end of the heel seat before the heel end of the upper is clamped to the sides of the last by a heel band i3 shown in broken lines in Figs. l and 3. The arm 29 is of considerable thickness, and as shown in Fig. 3 that portion of its lower face which is farthest from the extreme heel end of the shoe is rounded lengthwise of the shoe so that the rear portion only of the arm actually engages the upper and thus applies a firm localized pressure to the upper as the arm is carried inwardly over the margin of the sole.

The lower end portion of each arm 2l has a recess or notch at its inner side in which lies a horizontal cross-bar Si pivoted to turn freely on an upwardly extending pin 33 in the arm. The opposite ends of this cross-bar have rectangular metal-blocks 3ft (Fig. 3) projecting inwardly therefrom, and these blocks are covered by rubber pads 35. These pads are arranged to engage the inverted shoe upper just above its lower edge in locations spaced substantial distances apart lengthwise of the shoe where the side of the last slopes inwardly toward its top portion, and they thus assist in supporting the shoe and last against longitudinal and lateral tipping movements as well as against downward movement. Since the cross-bar Si is free to turn on the pin 33 when the lower end of the arm 2 is moved out of the groove 213 in the arm 23, the pads 35 are permitted -to assume positions in accordance with the contour of the side of the last, the turning of the cross-bar beyond predetermined positions being prevented by contact thereof with the arm 2l.

Each arm 23, while movable about its supporting` pin 2l, is arranged normally to occupy a substantially vertical position in which its rear side is in contact with a stop pin 3i projecting inwardly from an upstanding portion of the bracket Ii. For maintaining the arm 23 in this position, there is formed in the bracket II a short horizontal tubular guideway 39 (Fig. 3) in which is housed a spring-pressed plunger lll. This plunger bears against an inclined face on the lower end of the arm 23 just below the axis of the supporting pin and accordingly tends to swing the arm rearwardly and holds it ncrmally in contact with the pin The lower end face of each arm 2S is concentric with the axis of the pin 2l, and if it is desired for any reason to displace the two arms 23 from their normal upstanding positions when there is no shoe in the machine in order to permit, for example, better access to the heel band which is directly behind the arms, the arms may he swung forwardly about the pins 2l through aproximately into substantially horizontal positions. The spring-pressed plungers -i will then serve frictionally to maintain the arms in those positions until they are returned to their normal positions by the operator.

In the operation oi' a machine equipped with mechanism such as above described, the operator mounts a last and shoe on the heel pin 3 of the jack i when the jack is in its forwardly inclined position and then swings the jack rearwardly to carry the shoe into the open heel band 3, thereafter raising the jack by depression of its controlling treadle to position the heel end of the sole in contact with the holddown members 5, as hereinbefore described. The operator then starts the power operation of the upperis clamped at the sides of the heel endv machine, whereupon the forwardly extending arms I 0 of the bell-crank levers 9 are swung automatically inward toward the jack, the jack being also pulled farther rearwardly to press the end face of the shoe firmly against the heel band. As the arms i0 are thus swung inwardly, the inwardly extending arms 29 engage the margin of thevupper at the opposite sides of the shoe in locations approximately at the forward end of the heel-seat portion of the shoe and lay the margin over the sole if it has notalready been laid inwardly, and in any case press it firmly upon the sole, the supporting arms 23 at this time being in contact with the stop pins 3l. The rubber pads 35 also are carried into Yengagement with the shoe just above the lower edge of the upper in locations spaced apart lengthwise of the shoe forwardly and rearwardly of the locations where the arms 29 engage the shoe, the arms 2'! and 29 rocking about the pivot pins 25 to permit the pads 35 to be pressed against the sides of the shoe. In this operation also the cross-bars 3i may swing about their pivots 33 to permit the pads to assume positions determined by the lengthwise contour of the last. It will be understood that by means of the character disclosed in the previously mentioned Letters Patent the bell-crank levers 9 are operated in such manner as to press the pads 35 and the arms 29 firmly against the shoe, the rear portions of the arms 29 pressing the marginal portions of the upper materials firmly inward and down upon the sole and the pads 35 engaging the shoe with such pressure as not only to clamp the upper firmly against the last but also to hold the shoe and last firmly for the lasting operation.

After the shoe has been clamped by the arms 29 and the pads 35 as above described, the heel band 43 is closed about the heel end of the shoe to clamp the upper firmly against the sides of the last. As indicated in Fig. 3, the lower portions of the forward ends of the heel band are cut away to provide room for the rearmost pads 35 and to permit the arms 29 to be positioned close in front of the forward ends of the heel band. After the heel band has `been closed around the heel end of the shoe and while the arms i293k and the pads 35' are pressing against the upper, the heel-lasting wipers, which are shown in broken lines at 45 in Figs. l and 3, are advanced and closed over theheel seat to wipe the marginal portion of the upper inward over the sole. After the wipers have finished their wiping movements tacks are driven through them to fasten the upper tothe sole as disclosed in the previously mentioned Letters Patent. Just before the'wipers, however, reach their fully advanced and closed. positions their forward ends come into contact with the rear sides of the arms 29 and thus cause these arms to move `somewhat forwardly along the shoe in engagement with the upper, as indicated in Figs. 1 and 3, the arms- 23 swinging about their pivots 2l. Accordingly, the wipers near the end of their operative movements are in contact with thek proper-relation to the last and sole before the by the heel band and throughout the heel-endklasting operation, insurance is afforded against any objectionable displacement of the upper materialsl by the heel band and wipers.

It will be understood that after the shcehas been operated upon as above described, the wipers are withdrawn from over the heel seat and the heel band 43 is opened to release the shoe. The bell-crank levers 9 are also returned to their starting positions to carry the shoe-clamping means thereon away from the shoe, after which the jack is swung forward to itsidle position to permit the shoe to be removed.

In View of variations in the shapes of differentv shoes and in the character of the shoe materials, it maybe desirable to adjust the arms 29 upward or downward relatively to the holddown members 5 so that these arms will engage the shoe with the desired pressure. For this purpose the pins 25 which support the arms 21 and 29 have eccentric portions on which these arms are mounted, as indicated by dotted lines in Fig. 3. After loosening nuts 41 on these pins, the pins may be turned by means of a screw driver inserted in slots in their ends to adjust the arms 29 as required.
